eSignature Legality in India
Electronic signatures are legally recognized in India under the Information Technology Act, 2000, and carry the same legal weight as a handwritten signature for almost every type of commercial document.
Last reviewed: July 2026
Governing Law
Information Technology Act, 2000 (IT Act)
Two provisions form the legal backbone:
Section 5
wherever a law requires a signature, an electronic signature recognized under the IT Act legally satisfies that requirement.
Section 10A
contracts formed electronically are valid and enforceable, even where no specific signature method is prescribed.
Section 2(ta) defines "electronic signature" as authentication of an electronic record using a technique specified in the Second Schedule of the Act, and the definition explicitly includes digital signatures.
Indian Evidence Act, 1872 (Section 65B)
Electronic records, properly certified under Section 65B, are admissible in Indian courts on the same footing as physical originals, closing the loop between a valid signature and its usability as legal evidence.
The Two Recognized Categories
1. Digital Signatures (Section 3, IT Act)
Based on Public Key Infrastructure (PKI), typically issued via a USB token or Digital Signature Certificate (DSC) from a licensed Certifying Authority. The strongest, most formal category.
2. Electronic Signature Techniques (Section 3A, IT Act)
Techniques notified under the Second Schedule, most commonly Aadhaar eSign, which lets any Aadhaar holder sign using their Aadhaar number and an OTP sent to their linked mobile number. Introduced via the IT (Electronic Signature) Rules, 2015, Aadhaar eSign is overseen by the Controller of Certifying Authorities (CCA) under India's Ministry of Electronics and IT (MeitY), and produces a cryptographic PKI-based signature despite requiring no hardware or software installation.
For platforms and businesses not using DSC tokens or Aadhaar eSign directly, OTP-based or click-to-sign methods can still form valid, enforceable contracts under Section 10A, provided the underlying law doesn't specifically mandate an IT Act–recognized electronic signature.
When Indian eSignatures May Not Be Accepted
The IT Act's First Schedule lists a narrow set of exclusions:
- Wills and testamentary dispositions
- Trusts created under the Indian Trusts Act
- Negotiable instruments, other than cheques
- Powers of attorney relating to property
- Sale deeds and other documents requiring registration under the Registration Act (the underlying transaction itself, not necessarily every supporting document)
Outside these five categories, Aadhaar eSign and other IT Act–recognized methods can be used across essentially the full range of commercial documents, employment contracts, NDAs, vendor agreements, insurance applications, and more.

Questions, answered.
Common questions about eSignature legality in India.
Yes, for documents outside the IT Act's First Schedule exclusions. Inkfree's audit trail and authentication features are built to support the evidentiary standards Indian courts expect under Section 65B of the Evidence Act.
Under the IT Act, "digital signature" specifically refers to PKI-based signatures under Section 3 (like DSC tokens). "Electronic signature" is the broader category under Section 2(ta), which includes digital signatures plus other techniques notified under Section 3A, like Aadhaar eSign.
For most commercial contracts, a properly authenticated electronic signature (OTP-based, click-to-sign with audit trail, etc.) is enforceable under Section 10A, even without an IT Act–notified method. Aadhaar eSign or DSC becomes important when a specific law or government process explicitly requires an IT Act–recognized electronic signature.
Almost all. The only exclusions are the five categories in the IT Act's First Schedule: wills, certain trusts, negotiable instruments (other than cheques), powers of attorney for property, and documents requiring registration under the Registration Act.
